Patent EP-0037697-A1 (EP)
Inventor: EDWARDS PHILIP NEIL
IPC: C07C59/66
Filed: 1981-03-31
Abstract: The invention is concerned with novel dioxolane derivatives of the formula:-
     in which Ra is hydrogen or (1-4C)alkyl and Rb is (1-4C)alkyl or phenyl optionally bearing a halogeno substituent; their production; and their use for the manufacture of certain known anti-arthritic acids of the formula:-
     and, in particular, those acids in which Ra=Rb=methyl or Ra=ethyl and Rb =phenyl, by a novel reduction process. The preferred reduction procedures involve the use of an alkali metal borohydride or cyanoborohydride in the presence of a noble metal catalyst, or the use of an α-branched alkyl or cycloalkyl Grignard agent. 
     The use of the derivatives of formula avoids the need for potentially toxic reagents and reactive intermediates in the previously known processes for the production of the acids of formula V.

Abstract: Toy vehicles are known which have a steering system such that, when they are driven in one direction (usually forwardly) they travel in a generally straight line, and when they are driven in the opposite direction they turn. The application provides a way of achieving this, by providing on the vehicle an assembly (8) comprising two wheels (11, 12) supported by an axle (9) which is freely rotatable about a pivot axis perpendicular to the axle and spaced from the centre thereof, the axle being rotatable about said axis between a rear stop (14) and a forward stop (13). Articulated toy vehicles comprising a tractor (1) and trailer (2) have a drive means (4) installed in the trailer and stop means (16, 17) to prevent jack-knifing. Such articulated vehicles may be provided with a steering assembly (8).

Abstract: A rotating drum (1) for cooling and separating castings and molding sand has a foraminous liner (27, 8). In a first part (28) thereof there are sand raising vanes (17) between this liner (27) and the closed wall (28) of the drum to raise sand, passing through the perforations in this liner part (28) to spray it over the castings. In a second, more downstream part (8) of the liner this liner part (8) intersects the theoretical sand level (13, 14) to lift the castings from the sand, so as to discharge the castings via liner part (9) and discharge edge (10) separately from the sand. The sand separated from the castings is taken up in a closed end part (5, 7) of the drum (1) having a discrete discharge edge (11) for discharging the sand at the downstream end in a narrow zone. This gives a drum with high cooling and separating capacity and efficiency with the least possible noise and dust generation.

Abstract: A multipole edge connector for the electrical connection of strip contact surfaces of a flexible flat ribbon cable with the congruent edge contact surfaces of a printed circuit board having the same modular dimensions. The edge connector consists of a clamp-like holder which is fastened with holding means in the form of barbs on the edge of the printed circuit board, and which has a plurality of flexible tongues. To permit the preparation of the holder at low cost, it comprises two members which are cut off from two different metal strips with pre-punched and pre-embossed profiles, which members are joined together by welding in a perforated zone. The members are profiled to provide a cross section with a half-tulip-shaped, asymmetric clamping contour, whereby each of the flexible tongues provides a uniform contact pressure.
